DUST-PREVENTlN G APPARATUS FOR RAILWAY-CARS.

SEPBCIPICATION forming part of Letters Patent No. 373,622, datedNovember 22, 1887.

Application filed Novcmbcr26,1884. Serial No. 148,951. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES TURNER, a citizen of the United States, andresiding at Chicago, in the county of- Cook and State of Illinois, haveinvented certain new and useful Improvements in Dust-PreventingApparatus for Railway-Oars, which are fully set forth in the followingspecification, reference being had to the accompanying drawings, inwhich Figure 1 is a plan view of a railway passenger-coach having myimprovements applied thereto; Fig. 2, a side elevation of the same; Fig.3, an end view; Fig. 4, a detail sectional view on the line w 00 of Fig.2 and on an enlarged scale; Fig. 5, a detail sectional view on the liney yof Fig. 2; Fig. 6, adetail sectionalview on the line 2 z of Fig. 2,and Fig. 7 a de tail sectional view on the line o o of Fig. 3.

Like letters refer to like parts in all the figures.

My invention relates to apparatus for preventing the entrance of dustinto railwaycoaches, by means of which a thorough ventilation of theinterior thereof may be obtained without the annoyance attendant uponthe entrance of dust, smoke, &c.; and to that end it consists in certainnovel features, which I will now proceed to describe, and thenspecifically point out in the claims.

In the drawings, A represents the body of the car, and B the clear-storythereof. This clear-story is open at each end at b, and within the spacebetween the clear-story and roof proper B, at some distance from theopening I), a partition, 0, is arranged, preferably constructed asshown, with the sides inclined outward and toward the center of the car.At the point where this partition joins the sidcs of the clear-story isformed an opening, 0, communicating with a pipe, D, extending downwardto the lower edge of the car-body A, as shown in Figs. 2 and 3, where itconnects with a pipe, E, extending along said lower edge the wholelength of the car. One of these pipes, E, is arranged on each side ofthe car, and each pipe is connected with the clear-story by means of apipe, D, at each end. In the pipe E, near the under side thereof, isformed a slot, 6, opening out at an angle of about fortyfive degrees tothe vertical plane of the pipe, and at the upper end of each pipe D isarranged a hinged valve, (1, adapted to close the opening 0, whichconnects with the space C, within the clear-story, formed between itsroof and the roof proper B and the partition 0.

The operation of this device is as follows: \Vhen the car is in motion,the air will enter the space 0 at the opening I), at that end of the carwhich is the front end, and which in the present instance is supposed tobe the end shown in the drawings. The air being driven forcibly into thespace 0 by the motion of the train, will be guided by the inclined sidesof the partition C to the openings 0, will raise the valves (1 at thatend of the car, and pass through the pipes D and forcibly out throughthe slots 6, all in the manner indicated by the arrows in the severalfigures, the valves (2 at the rear end of the car being closed by thepressure of the air in the pipes D at that end, so as to prevent the airfrom passing out at that end, instead of through the slots 6. By thismeans a sheet of air, moving at ahigh rate of velocity, is interposedbetween the under side of the car and the upper portion thereof, inwhich the windows, doors, and other orifices are located, so that noneof the dust raised from the road-bed by the commotion caused by thepassing train will be able to ascend 'to the windows and doors, andthence into the car, but will all be retained underneath the car-bodyuntil the train has passed. The other end of the car, which is not shownin the drawings, will be similarly constructed, so that when the car ismoving in the opposite direction a current of air will issue from theslots 6 in the manner just described.

In order to further protect the car-windows against the entrance ofsmoke, dust, or cinders, I arrange upon the side of the car, between thewindows, several groups (in the drawings only one is shown) consistingof two pipes, F F, slotted as shown at f, these slots being arranged atan angle of about forty-five degrees to the line of motion with the carand in opposite directions. At the upper end the pipe F is connectedwith a suitable funnel, F opening toward one end of the car, and a pipe,F, with a similar funnel, F opening toward the other end of the car. Thetwo pipes may be connected at their lower end with a short pipe, F,connecting with the pipe E. When the car is moving in the directionhereinbefore mentioned, the air will enter the funnel F and be forcedinto the pipe F, from whichit will issue forcibly in a sheet through theslotf, as indicated by the arrow in Fig. 6. This sheet of air willeffectually prevent any dust or cinders from entering the windowsimmediately in the rear of it, and I contemplate providing each car witha sufficient number of these groups of pipes to effectually shield allthe windows. It will readily be understood that when the car is movingin the opposite direction the pipe F will operate in asimilar manner andeffect the same result as the pipe F with regard to the windows in therear of it. G indicates a plate or shield arranged between each pair ofpipes F Fand projecting slightly outward beyond the same to prevent thestationary body of air surrounding the moving train from too abruptlybreaking in upon the sheet of air issuing from the slot f, this shieldalso acting as an additional support, to which the pipes may beattached.

In order to prevent the dust which is retained underneath each car bymeans of the air issuing from the pipes E from rising in the spacesbetween the car, I attach under each platform an inclined guard, H, asshown in Figs. 3 and 7, extending down to the level of the lower step,and hinge-to the lower end of this guard a swinging shield, h. The airand dust underneath the car will be deflected downward by means of theinclined guard H under the rear platform, the shield h swinging outward,as indicated by the dotted lines in Fig. 7, to permit its escape, whilethe corresponding shield, 72, will swing in the opposite direction orinward, as indicated in dotted linesin Fig. 7, to permit the dust andair to pass underneath the next car. Owing to the downward directiongiven to this dust laden air by the guard H and shield h, itdoes nothave timeto rise between the two cars, but passes immediately under thefollowing one, where it is retained, as hereinbefore described, and soon until it passes out at the rear end of the train.

In order to prevent any dust, smoke, or cinders from entering betweenthe cars from above, I attach to each end of the car roof,

along the upper edge thereof, a pipe, I, slotted at i and connected ateach end to a funnel, I. The air entering these funnels I willbe forcedinto the pipe I and thence outward and upward through the slot 2', so asto deflect any cinders or dust which would otherwise pass down betweenthe cars and be liable to enter through the doors or windows.

In the sides of the clear-story are arranged the usualventilating-orifices, J, inorder to protect which I hinge at each end ofeach orifice a swinging dust-shield, J, the motion of which is limitedby means of stops consisting of pins or other projections j, arranged inthe path of motion of the shield. These shields deflect any cinders ordust which would otherwise enter the car through the ventilators J,their action being autOmatic i. 6., upon a change in thedi-rection ofmotion ofthe car they will swing automatically from the position shownin full lines in Fig. 1 to that shownin dotted lines in the same figure,so as to effectually protect the ventilators in either case.

It is obvious that various mechanical modifications in the constructionshown and described may be made without departing from the principle ofmy invention, and I therefore do not wish to be understood as limitingmyself precisely to the details of the construction set forth.

I am aware that slotted pipes, into which vent the entrance of dust intocar-windows, are not new, the same being shown in Letters Patent No.175,569, granted April 4, 1876, to Charles G. Lea, and in Letters PatentNo.

Driesbach. I am also aware that pivoted deflectors arranged to shieldthe ventilating-orifices in the clear-story of a railway-car are notnew, the same being shown in Letters Patent No. 123,770, grantedFebruary 20, 1872, to William G. Creamer. I therefore do not wish to beunderstood as claiming either of these constructions, broadly.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
